Roger Hertzler (N/A–) is an American preacher and writer whose ministry within Anabaptist circles emphasizes radical discipleship and practical Christian living, particularly through his focus on biblical stewardship and evangelism. Born and raised in the United States—specific details about his early life are not widely documented—he resides in Halsey, Oregon, where he is affiliated with Valley Christian Fellowship. Converted to Christianity, Hertzler has dedicated his life to sharing the gospel, notably through street witnessing with gospel signs, a passion that led him to found Watchman Gospel Signs, offering low-cost tools for evangelism. Hertzler’s preaching career is marked by his thoughtful sermons and writings, including books like Through the Eye of a Needle and How to Shake the World With $100, which challenge believers to reject materialism and pursue treasures in heaven. His messages, available on platforms like SermonIndex and Anabaptists Live, often address themes of wealth, sanctification, and outreach, as seen in talks like “Treasures in Heaven” and his article “Mission to the Telemarketer,” reflecting a burden for unconventional evangelism. While not a high-profile figure, his ministry influences Anabaptist communities through teaching and personal example, leaving a legacy of simplicity and gospel-centered living. Personal details, such as family, remain private, but his work continues to inspire a return to New Testament faith principles.
